Party $33 -- multi-tabling....does anyone else do this?

[trojanFan]

New at multi-tabling....I'm comfortable with 4 at a time.

At 20 minutes into the set of 4....I open up 4 more new sng's but put them on "post blind/fold" - and put them in the background until I'm ready for them. I usually miss level 1 and 2 on them, join them with 700-725 chips in level 2 (late) or early level 3. I end up completing about 10-12 sng's per hour doing this.

Is this serious -EV?

Input is appreciated!
